Description

The launcher protective device
Technical field
The utility model relates to a kind of automobile impact test apparatus, especially relates to a kind of vehicle impact testing protective device.
Background technology
The pedestrian is the disadvantaged group in the traffic hazard, the easiest coming to harm.According to World Health Organization's statistics, the annual whole world has 1,200,000 people to die from road traffic accident approximately, and wherein 46% is pedestrian, cyclist or two-wheeled vehicle user, and this ratio can be higher in some low incomes and middle income country.China's road traffic condition complexity, people, the parallel situation of car are many, are in the world typically based on the country of mixed traffic, and death toll is at the forefront in the world in the Road Traffic Injury.So it is particularly important, urgent in China how to improve pedestrian protecting performance, the reduction pedestrian injures and deaths of automobile.In order to reduce pedestrian's injures and deaths in the traffic hazard, the experimental technique of pedestrian protecting notion and pedestrian protecting has been proposed, by simulation test, make vehicle have better pedestrian protecting ability.At present, general in the world means of testing is " dot type " test method, promptly adopt the test method with the simulator vehicle impact different parts of human body different parts, pilot project comprises that simulation impact on legs bumper is tested, simulation thigh bump hood leading edge tests and analogue head bump automotive hood is tested 3 types.In the impact test of simulation shank, the model of simulation shank clashes into bumper by launcher with 40km/h, and 3 diverse locations are got in test ready, and the data of collecting by the simulated leg type are assessed the extent of injury of leg type about the pedestrian then.Because the shank model velocity ratio of being launched out is very fast in test; this can produce the phenomenon of shank model bounce-back with regard to inevasible; can cause the shank model to rebound back on the launcher; damage launcher; usually the launcher front is not placed protective device and is protected launcher, so a protective device is set with the protection launcher before launcher.The Chinese utility model patent instructions of the CN201397267Y that on February 3rd, 2010 was announced discloses a kind of adjustable test protective shield; this adjustable test comprises baffle plate with protective shield; two bracing frames and adjusting screw; all have row's circular hole on the both sides of described baffle plate and the bracing frame; baffle plate is fixed on the bracing frame by circular hole; baffle plate can be regulated by being fixed on the different circular holes at the height on the bracing frame; the bottom of described bracing frame is a screw thread; the threaded engagement of described adjusting screw and support bottom; can finely tune the height of baffle plate by adjusting screw; this adjustable test is used for protecting the testing crew of tension or compression test with protective shield; prevent testing crew because the part material collapses and damages in the test specimen; when but this adjustable test is used in the launcher of protecting in the impact test of simulating shank with protective shield; since the shank model launch and bounce-back speed very fast; moving this adjustable test with hand uses protective shield speed slower; before this adjustable test can't in time move on to launcher with protective shield, thereby can't play protective action.
Summary of the invention
When the utility model mainly is the launcher that solves in above-mentioned adjustable test is used in protection simulation shank with protective shield the impact test; since the shank model launch and bounce-back speed very fast; before this adjustable test can't in time move on to launcher with protective shield; thereby can't play the protective action problem; a kind of launcher protective device is provided; this launcher protective device not only can well play the effect of protection launcher, and uses flexibly.
In order to solve the problems of the technologies described above; the utility model has adopted a kind of like this launcher protective device; comprise the fixed bar that a baffle plate and an end are fixedlyed connected with launcher; the other end of described fixed bar is fixed on the medial surface of baffle plate; the centre of described baffle plate is provided with launches the hole; describedly launch the shape in hole and shank model that launcher is launched coincide; described baffle plate is used to protect launcher; prevent that shank model that launcher launches from rebounding back on the launcher; damage launcher; launch the hole in the middle of the described baffle plate; described shank model ejects from launch the hole; described hole shape and the shank model of launching coincide; like this after the shank model is rebounded; it is almost nil to pass the probability that bumps against launcher from launch the hole; described fixed bar is two; one end of fixed bar is separately fixed at the left and right sides of the medial surface of baffle plate; slot milling is used to avoid the shank model in the middle of the baffle plate; the other end of described fixed bar then is fixed on the launcher, and the launcher protective device just can move with launcher like this.
As preferably, the described hole of launching is provided with shutter, and described shutter is connected with spring hinge with baffle plate on one side.Described shutter is used to block and launches the hole, to pass probability be zero from launching the hole in the back to guarantee to rebound the shank model, described shutter is connected with spring hinge with baffle plate on one side, at the trial, earlier shutter is drawn back, after the shank model is launched frame and ejects, unclamp shutter from launch the hole, shutter can be under the spring hinge effect return, cover and launch the hole.
As preferably, the vertical fixing of the medial surface of baffle plate has stiffening plate, described stiffening plate is in the inboard of fixed bar, be fixed with web joint between described fixed bar and the stiffening plate, described web joint is " recessed " font, one side of two projectioies of the font web joint of described " recessed " is fixedlyed connected with stiffening plate, and described " recessed " font web joint opposite side is fixedlyed connected with fixed bar.Described stiffening plate is used to strengthen strength of joint and the stability between fixed bar and the baffle plate, described " recessed " font web joint is four, certain elastic deformation can take place in described " recessed " font web joint, guarantees the connection stability of fixed bar and stiffening plate and web joint.
As preferably, described fixed bar xsect is a rectangle, and described fixed bar has rectangular through slot on two adjacent sides of length direction.Described fixed bar is the aluminium alloy rod of rectangle, and fixed bar can not rotate locating fixedly the time with baffle plate and launcher like this.Described fixed bar in four sides of length direction, wherein on two mutually perpendicular sides rectangular through slot is arranged, described rectangular through slot be used for launcher go up fixedly that the rectangular preiection of fixed bar matches, play the role of positioning.
As preferably, the described notch cuttype of upper end that launches the hole for inwardly shrinking.Describedly launch the shape in hole and shank model that launcher is launched coincide, the upper end of launching the hole can conveniently process for the notch cuttype that inwardly shrinks.
As preferably, described baffle plate is that organic glass is made.The material of described baffle plate uses transparent organic glass, can the handled easily personnel observe when playing protective action.
The beneficial effects of the utility model are that this launcher protective device not only can play the effect of protection launcher in the impact test of simulation shank, and easy to use flexible.
